DEVICE FOR MONITORING ICING FORMATION ON LIGHTNING PROTECTION CABLES OF OVERHEAD POWER LINES 110-220 kV Russian patent published in 2019 - IPC H02G7/16 H02J7/35 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and electric power engineering and can be used for monitoring of icing on lightning protection cables of overhead power lines of electric networks with voltage of 110–220 kV. Essence of the disclosed solution lies in the fact that in the device for monitoring icy-formation on lightning protection cables of overhead lines in 110–220 kV supplying electric networks, consisting of parallel means for removing primary information on angle of longitudinal deflection of lightning protection cable, transverse angle of lightning protection cable deflection, lightning protection cable temperature, signal processing means, information transmission means and information receiving means, according to present invention, means for removing primary information on lightning cable sag angle is in form of inclination angle sensor, signal processing means comprises series-connected analogue-to-digital converter, digital signal processor, and information transmission device comprises interface connected to data transmission means, wherein the information receiving means is connected to the lightning cable deflection visualization means, and the signal processing device is connected to the information processing means, which is connected to the additionally introduced power supply based on the flexible solar panels, connected in turn to the digital signal processor.

EFFECT: possibility of remote detection of a section of a lightning protection cable with ice, high reliability of powering devices by using flexible solar panels and avoiding the need for high-altitude installation works for periodic replacement of discharged accumulators, as well as the possibility of expanding the zones of arrangement of the device both on cables with voltage, and lightning ropes without current load.
